OIL BURNER.

' -App1ication filed December 21,1921. Serial No. 523,980.

T 0 all whom it may concern:

Be it known that I, Josnrn A. Trimmers, a citizen of the United States, and a resident of Oakland, county of Alameda, and State of California, have invented a new and use ful Oil Burner, of which the following is a specification.

My invention. relates to oil burners and has for its primary object to provide a burner which is simple in construction, cheap to make, yet embodying certain important mechanical principles which enable it to carry out its intended use withthe greatest of efficiency, and accomplish results which have heretofore been absent in devices of this character.

In the accompanying drawing I have illustrated the preferred embodiment of the invention and the same will. be used as a basis of explaining the salient features of the invention throughout the following detailed description.

In said drawing, Figure 1 is a plan view partly in longitudinal section of the device assembled, and Figure 2 is a longitudinal section of the nozzle.

Referring now to the drawing in detail, I propose to provide a mixing chamber (1), produced preferably from a three-way union so that it may be introduced into the chamber through an inlet pipe (2) screwed into one end of the union with the oil introduced into the chamber through an inlet pipe (3) screwed in the top of the union. The opposite open end of the union is made to receive a plug (a) with the plug adapted to be screwed into the open end of a second threeway union The top opening' of the union (5) is made to receive an inlet pipe (6) so that steam maybe introdiu-ed into the chamber (7) formed by the union. Screwed into the opposite end of the union (5) is a pipe or casing (8). the opposite end of which being received in the end of a nipple (9) which also carries a plug (10) with the plug protruding beyond the end of the nipple (9) and made to be threaded into the side opening (11) of another three way union which carries the nozzle, the de tails of which will be presently described.

Housed within the pipe or casing (8) a tube (12) which comprises a restricted communication between the mixing chamber (1) and the receiving chamber of the nozzle formed by the last mentioned three way union. The pipe or casing is made to provide a superheater for the mixture as it passes through the restricted communication (l2) and to block off the pipe or casing at its respective ends. The plug (4.) has an axial bore which is made to receive the tube which forms the restricted communication (12) so that the open end of the tube may communicate with the mixing chamber (1) and at the same time block off the mixing chamber (1) from the pipe or casing (8). The opposite end of the pipe or casing (8) is blocked off in a similar manner by the plug (10), as previously meI1- tioned. This enables steam to be introduced through the inlet pipe (6) to the casing (8), and to relieve the water of condensation a valve (14) is arranged as shown in Figure 1.

The end of the plug (4) within the mixing chamber (1) is dished out as shown and the tube (12) is raised or otherwise lined in the bore of the plug to make a perfectly tight fit. The end of the tube (12) which terminates in the receiving chamber (13) of the nozzle is turned at right angles so as to leave a discharge pointed in the direction of the discharge end (15) of the nozzle (16). The nozzle (16) preferably comprises a cylinder with the discharge end (15) thereof made with a beveled seat adapted to correspond to the frustum shaped valve head (17) which is carried on the end of the core insert (18) and adapted to be adjusted relative to the beveled seat of the discharge end (15) of the nozzle to control the effective port area of the discharge to a nicety. Adjacent the valve head 17) is a spiral fluted sleeve (19) which is mounted with freedom of rotation on the restricted end (20) of the core insert with the spirals thereof arranged at a slant to the axis of the nozzle so as to communicate with the spirals (21) of the core (22). The core (22) is of substantially the same diameter as that of the inside dimensions of the cylinder so that the mixture is caused to take a tortuous passage in reaching the fluted sleeve (19) where it will be released through the discharge end of the nozzle in a whirling motion, thus resulting in a fine mist which is readily ignited and very easy for the flame to totally consume all of the products of the mixture, leaving no smoke or carbon.

The core (22) terminates in the threaded stem (23) which extends through a stuffing box (24) in the plug which closes one end of the three-way union whereby the core insert maybe turned in a clockwise or anticlockwise direction so as to adjust the valve head (17) relative to its, seat in the discharge end of the nozzle for controlling the flame. The cylinder of the nozzle is preferably threaded into the opposite end of the union from the plug (25) as best'shown in Figure 2. The gradual taper of the stem in creases the area of the receiving chamber (13), as best shown in Figure 2, which is highly desirable for the results to be accomplished.

From the above it will be readily seen that I have provided a mechanically perfect solu tion of the problems involved in a burner 01 this character, and furthermore it is to be likewise noted that the device may be.

made up practically from standard :fittings, which cheapens lts constructions and which will enableit to be offered on the market at and the nozzle, a super-heater for said tube comprising a casing extendingsubstantially thelength of the said tube and surrounding the same, and a steam inlet into said casing, said nozzle comprising a cylinder havinga receiving chamber in one end'and a discharge at its opposite end, a core insert for said cylinder, said core insert including a stem extending through one end of the receiving chamber, the intermediate portion of saidcore insert having a diameter of substantially that of the inside diameter of the cylinderand spiral grooves'in said intermediate portion, a reduced portion in front of the intermediate portion, a spiral fluted sleeve mounted with freedom of rotation on said reduced portion, and a frustum shaped valve head on the extremity of the core insert in front of said spiralfiuted sleeve, said head adaptedto adjustably control the port areaaoi the discharge end of the nozzle with a seat in the discharge end of the nozzle made to correspond with the frustum shape ofsaid head.
